A sarcastic term for someone who is an Internet "tough guy." A person who spends most of their time on Internet message boards acting like they are the all-knowing and all-mighty. If someone disagrees with their opinion the person labels the person with whom they disagree with a "sheep", "sheeple" or called some sort of derogatory term. This person tends to have very few friends in the real world and makes most of their friends on the Internet with people who are similar to themselves.

Person: I think that he's a really good coach.
Internet Hero: He's such a terrible coach, you're such an idiot! Wake up sheeple he needs to be fired!!

That guy who clearly spends too much time on the forums. His posts are generally characterized by a snooty tone, good grammar, and overuse of "..." and "-_-". The Internet Hero is often targeted by hoards of trolls but never realizes it, concluding that his spectacular intelligence makes everyone else a heathen.

Internet Hero: *Long-winded, arrogant post*
Heathen: But that doesn't make any sense.
Internet Hero: Just because you're too much of an idiot to understand my logic doesn't mean it doesn't make sense.
Everyone Else on the Forum: It doesn't make sense.
Interent Hero: Lol, whatever...why are there so many idiots on this forum? -_-
